It was easy to install
It was easy to install except that I had an existing flexible hose that I was not able to unscrew, and I had to get a new one because it was leaking water when I turned on the water supply. I had to run to the hardware store to get a new flexible hose that attached to my water supply and then I was good to go.
I still have to get use to using it and for how long to use it, because it doesn't get my butty clean enough.
